Specification of Letters Patent.

Patented Mar. 3d, IQiId.

Application filed September 20, 1913. Serial N 0. 790,890.

To all whom it may concern:

Be it known that I, Louis M. DU CoMMUN,

a citizen of the United States of America, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Air- (Jonditioning Systems; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to new and useful improvements in air conditioning systems.

The object of this invention is to provide an air conditioning system particularly adapted to auditoriums, work-shops and drying-rooms of large size, and as a modification of the invention disclosed in my copending application, Serial No. 751,704, filed March 3rd, 1913.

My invention therefore consists in certain novel features of construction and combination and arrangement of parts, described in the accompanying specification, pointed out in the claims, and illustrated in the accompanying drawings.

In the accompanying drawings Figure 1 is a vertical section through a room provided with an air conditioning system embodying my invention. Fig. 2 is a section on line 2-2, Fig. 1. 1

Again referring to the drawings 10 represents the floor of a room, which may be a public-hall, a work-shop or the drying-room of a factor 11 represents the walls of the room and 13 the ceiling. At each side of the room is arranged a partition 14: which is spaced a predetermined distance from the adjacent,

wall 12, and the said partition is preferably made removable so as to give access to the space between the said partition and adjacent wall when necessary. The said partitions 14: do not extend entirely to the ceiling so that there is a comparatively large opening between the top of each partition and the ceiling. The space between each of the partitions 14 and the adjacent wall of theroom, indicated at 20, I will term a purifying chamber. In the bottom of each purifying chamber 20 are arranged a series of steam pipes, the said pipes being preferably grouped in the form of a pyramid, as shown at 21. Near the bottom of each purifying chamber 'is formed an opening 22 which places the purifying chamber in communication with the said room and an opening 23 which places'the purifying chamber in communication with the outer air. In each purifying chamber 20 is arranged a vertical series of water troughs, shown at 30, which may be supported in any suitable manner,

and in the drawings I have shown them resting on supports or rods 31. Each trough extends practically the full length of the purifying chamber and has a width somewhat less than the width of said chamber. These troughs 30 are mounted one above the other and are spaced a short distance apart vertically and are arranged in staggered formation, the alternate troughs starting from the topmost trough being arranged close to the outer wall of the purifying chamber and the other troughs being arranged close to the inner wall of said chamher. This arrangement completely cuts 0H any circulation of air between the walls of the chamber and the troughs adjacent thereto, the only passageway for the air being formed by the'vertical spaces between the troughs and the spaces between each trough and the wall of the chamber farthest from the troughs. It will, therefore, be seen that the air passing through said chamber must follow a sinuous course which carries it alternately from side to side of the chamber and as it passes from side to side it passes over the top of a trough so that when it reaches the opposite end of the air chamber it has been carried overthe tops of all the troughs in the chamber. In each of the troughs 30 is arranged an overflow drain pipe 33, the lower end of which extends down over the next lower trough so that the water from the uppermost trough is able to flow down to the next lower trough and from that to the next lower trough and so on down, the lowermost trough overflowing into a drain pipe, shown at 34:, which preferably connects with the sewer. A water supply pipe 35 is provided for supplying water to the uppermost trough.

Above and extending longitudinally and in close proximity to each trough is arranged a series of steam pipes 36 and above each series of steam pipes 36 is mounted a deflector 37 which is supported by means of a small bracket 38 from the supports 31. The purpose of these defle ctors is to deflect the heat from the steam pipes down onto the surface of the water in the troughs. In each trough is also arranged a steam pipe 40 so that the said pipe Will be submerged when the water is at the normal heightrin the said trough.

The operation. ofmy system is as follows :Water from the supply pipe 35 is permitted to flow into the uppermost trough from which it overflows to the next lower trough and so on down until all the troughs are filled with water. After the troughs have been filled the Water supply is regu-- lated-so that there will be a continual flow of water sufficient to carry off any scum or deposit which may accumulate on the surface of the water in the troughs. Steam is then admitted to the pipes in the troughs and also to the pipes above the troughs and the passage of the steam through the former will heat the Water in the troughs, but the temperature of the steam must be regulated so that the water in the troughs will not be raised to the boiling point, as the water must only be heated to such a temperature as will produce comparative rapid evaporation with the generation of steam. The steam pipes inthe bottom of the purifying chamber heat the adjacent air causing it to rise through the purifying chamber until it reaches the top of the purifying chamber where it again passes out into the room. As the air passes through thepurifying chamber it must'traverse the surface of the water in the various troughs and being thusforced into intimate contact with the water all the impurities carried by the air will be absorbed therefrom and left on the surface of the water. It will be understood that as the air passes over the troughs it will, of course, pick up a certain amount of moisture so that when the air again reenters the room the air will not only have been purified but will also have the proper degree of humidity necessary for the comfort and health of the occupants of the room.

It will be further noted that by being able to supply any degree of humidity to the air I am able to apply my system very successfully to drying-rooms of paint-shops, and the like, for as is known to those conversant with the art, the quickest and best results, in the drying of all materials containing volatile oils and the like. are obtained when a certain amount of humidity prevails in the air of the drying-room, as the moisture in the air prevents an outer crust from be ing formed on the paint before the innermost portion has become oxidized or dried.

\Vhat I claim is,-
